this growth

After vomiting for a long time, the mouths of the two little ones were still full of ashes. It was only when Du Nan found them and quickly handed them the water bottle that they spit out the black ash from their mouths.

Finally, I looked at the cup I used to gargle: in the teacup with only half of the water left, there was a layer of ash floating on the top and a layer of sediment on the bottom. Although they were all black, the ones at the bottom of the cup were not ash, but Is it a... black liquid?No, if you look carefully, you will find that it should not be liquid, but a layer of extremely fine black powder.

Look at the original location of the black fragment - empty!

Huajiao turned his head immediately: "You succeeded!"

Du Nan nodded: "It seems to be."

Bajiao was half a beat slower, and it took a long time to realize that the black ash that floated down from the sky was roughly equivalent to the original black fragments, but how could it be roughly equal?Obviously one is so hard, but the black ash is what those plants bloomed before, isn't it?

It was Du Nan who saw that he didn't understand, and took the initiative to explain: "This fragment is too strong, I am afraid that the existing fire can't melt it, so I used other methods to break it down."

"...This is the golden jade flower. The golden jade flower grows extremely fast and likes to take root in the metal. It is the continuously growing golden jade flower that separates it, and during the growth process, the substances that make up the black fragments are deposited on the golden jade flower. Among the rhizomes and flowers, things must decay to the extreme, and after such reciprocal growth reaches a fixed cycle, they will wither automatically, I just used magic to speed up the progress--" I don't understand, but it doesn't prevent Bajiao from thinking that Du Nan is very Great, nodded, and when he looked at the bottom of the cup again, Bajiao felt amazing.

But it was their choking that reminded Du Nan how to collect the black foam formed by these fragments.

These black foams sink when exposed to water, but the gray-white incense ash on the ground will hang in the water. Taking advantage of this characteristic of black foam, Du Nan moved out all the containers in the storage bag, and Huajiao pointed the way. They found a water source nearby, and then they used the wind to blow away the remaining plant ash on the ground, then put the black foam that settled in the gray soil into a container filled with water, stirred it, and then collected the black foam that settled at the bottom , Du Nan was the main force, and Zanthoxylum anise was also helping. This was repeated several times until the extracted black foam was quite pure. Du Nan dried it and finally got a bag of pure black foam.

Not much, but definitely a masterpiece.

Presumably the original complete body of the fragment was not made of this black powder.

Carrying the bag containing black foam, Du Nan looked around: there was water, fire, and materials...

Suddenly blessed to the soul, he felt that he could start work.

Just do it, and Du Nan is ready to practice immediately.

The body of the urn was designed long ago, but the selection of materials has not yet been finalized. However, when Du Nan arrived here, he suddenly felt that he did not need to search for materials, as the most suitable materials were already available here.

He mixed the grayish-white soil on the ground into water. He originally wanted to mix it with the black powder, but soon found that it was a bit difficult. After a moment of contemplation, he took out a bag of primary soil from the storage bag.

In fact, it was just another sudden idea, but this time, the off-white soil that was added to the primary soil was quickly mixed with the primary soil, and the first step was successful, and when he mixed the black powder into it, it went just as smoothly .

It is also a coincidence that Du Nan hit by mistake, and it is not an exaggeration to say that it is a coincidence-the first soil, as the first soil in the world, all the soil in the world comes from it, and the native metal, the first metal in the world also comes from it. It comes here, and it is not an exaggeration to say that it is the best adhesive in the world, especially when the material of the refining tool is mainly clay metal, the first soil can be said to be the strongest auxiliary material in the refining process!Among the many advantages, the first soil has an advantage that is especially suitable for the current situation: it can automatically adhere to the gold-soil substance, and the amount of sticking varies according to the properties of the gold-soil substance, but there is only one thing, that is—— It sticks a fixed amount of gold and earth substances!

For example, at this moment, after Du Nan poured the primary soil, as he kept stirring, each grain of primary soil automatically adhered to ten grains of gray-white soil, and at the same time, three grains of black powder adhered to it. After stirring until the end, Du Nan Nan was surprised to find that he got a piece of material with extremely uniform distribution of various materials? !

He vaguely knew that this was Chu Yang's role.

The most difficult step for a novice has been completed, and he can then make embryos.

He did this step purely by hand, feeling every inch of the embryonic body with his hands, his palm prints were printed on every part of the embryonic body, and at the same time, a large urn was formed under his palm.

The appearance of this urn is no different from that of ordinary households outside, but there is a mystery inside.

Du Nan reserved a total of 99 fire holes on the body and bottom of the urn, and each drop of fire was enclosed in a clay pellet made of the same material as the body of the urn, and each pellet had a movable device. It can be opened and closed according to Du Nan's wishes.Of course, at this stage, he can't control these many fires, he just reserved the fire places.

As for the current stage, he is still using the nine circles of fire at the bottom of the urn.

The fire seed in the center of the circle is naturally the most powerful fire seed he has obtained so far-transparent fire.

The surrounding eight circles are divided into different categories. He embedded star anise peppers in the past two days to help him collect various types of fire, and each circle has different opening methods. You can choose three-point opening, four-point opening, eight-point opening...or even open all of them. .

After embedding all the flames, Du Nan will really start refining the weapon.

It's just that the weapon he needs to refine now is the refining furnace that he will use for refining in the future. Without a refining furnace, how would he refine it?

Du Nan was blessed again.

Sitting by the river with Star Anise Zanthoxylum bungeanum and drinking soup, he looked ahead to the cave leading to the place of fire, and suddenly had a very bold idea in his mind-their current position is like this: they are currently leading to the place of fire Outside the cave, there is a waterfall here, and under the waterfall is a large lake. This is the source of water that Zanthoxylum took him here before, but it is not the same way as when he came here.

From this direction, Du Nan could easily see the cave they had entered and exited several times before.

And that cave is just halfway up a mountain...

Suddenly thought of something, Du Nan hurriedly ran towards the cave, and came back to the fire, he just looked up, and when he saw the rock above, he knew what to do next.

Du Nan decided to use the mountain as a furnace and all the fires in the cave as a flame, so as to refine the big urn he had just completed.

This idea sounded unreliable at first, but as Du Nan walked around the mountain a few more times, he felt more and more that this might be the most feasible way at present.

Who made this mountain look like a stove?

And this mountain has only one cave, which is the cave where they found the fire seed before. Besides, let alone the cave, this mountain doesn't even have a crack. Who would believe it? !If Du Nan hadn't climbed up and down to study the mountain thoroughly, he would not have believed it.

In this way, as long as he adjusts the placement of the fire seeds on the ground inside to form a huge magic circle, and then arranges a suitable wind magic circle at the entrance of the cave...

Wouldn't the fire in there really be able to burn?

Just do it, Du Nan acted again.

Climbing to the top of the fire place to look at the position, Du Nan adjusted the clusters of flames to a suitable position, and used the fire here to build an extremely large fire control array. It was impossible to open the large formation at once, so he even drew a small formation under each fire seed.

There are 540 drops of fire here, so Du Nan drew 540 small magic circles. It is also thanks to the many magic circles he copied a while ago. Copying day and night, even if Du Nan came up with this idea, I am afraid that he will not be able to realize it.

However, he had spent so many days imitating it, only drawing each magic circle, large and small, meticulously, and he could not make mistakes with his eyes closed.

The right time, the right place, the right people - now he has everything!

Finally, Du Nan finished drawing all the magic circles. The cave, which had nothing but white clay flames, has now become a place of magic circles. Even Du Nan drew the most basic fire control circles, but tens of thousands of rules The entire fire control array appeared together, which looked incomparably spectacular.

After finally confirming the accuracy of all the magic circles, Du Nan looked at Bajiao: "Have all the beasts on the mountain been driven away?"

Bajiao immediately patted his chest and reassured: "Don't worry, Daddy, I have patrolled the whole mountain a hundred times on Xiaohong, and I promise there are no wild animals."

Although it wasn't there originally.Maybe it's too hot in this place - Bajiao thought.

Nodding, Du Nan then looked at Huajiao: "The flowers and plants in the cave have also moved out?"

Huajiao pointed to the piles of red and green hay behind him: "It's all here."

Du Nan smiled slightly: "Thank you for your hard work."

After speaking, he looked in the direction of the cave, the smile on the corner of his mouth gradually narrowed, and his whole person became more solemn at the same time.

"Then, let's start." As he said, Du Nan stretched out his finger, and pointed his slender index finger to the sky, while the other four turned simultaneously, drawing a wonderful hand formula in the air.

The first fire control formula was opened, and in the cave, on the first small magic circle, the flames that were burning silently suddenly shot up.

Then, the second, third, fourth...

Du Nan repeated the "Firing the Fire Art" boringly.

In his opinion, he is not a very smart person, nor does he have much ability. In his opinion, the only thing he is okay is that he can endure mechanical labor, right?

Then, he still has the physical strength to withstand long hours of mechanical labor.

The good physical strength he trained in Hedu and Zhendongjie perfectly supported his spellcasting process for such a long time.

Because he only chose the simplest fire control formation, so it doesn't take much aura to create this formation, especially the aura here is already abundant, even if it's not on the spirit veins, the aura here is better than the ones Du Nan has been to before. Intense anywhere.Basically, the aura automatically introduced by the body is enough for him to use.

Du Nan beat his hands tirelessly like this.

When star anise pepper was eating, he was doing hand tricks; when they were playing, he was doing hand formulas; when they were sleeping, he was still doing hand formulas.

During this period, there was nothing wrong with any movement of his fingers. Even though the speed of his hand formulas could be further improved with the improvement of his proficiency later, he did not speed up, but maintained the original speed steadily, moving each The movements are all accurate to the limit, and by the way, take a break in the slightly slower movements.

This fight lasted for seven days and seven nights. After the last hand formula was played, Du Nan almost held his breath.It wasn't until he saw the whole formation in motion that he was sure that he had finally succeeded!

No, it cannot be said to be successful, it can only be said that he successfully activated all the magic circles.

Next, we can only wait.

When designing with Zanthoxylum before, they screened out many formations, but when actually making the urn, he didn't engrave any formations.

So now, when the fire formation is activated, Du Nan, who doesn't use the seal carving formation, has nothing to do.

It was only at this moment that he felt tired.

Sitting on the ground, Du Nan directly sat down on the spot.

This meditation is another seven days and seven nights.

As if sensing something, Du Nan, who had been closing his eyes to repair himself, suddenly opened them.

Then—the ground shook slightly at first, and then the vibration became bigger and bigger. Just when Du Nan thought that the ground would shake and the mountain would collapse in the next second, the violent vibration suddenly stopped.

Accompanied by a loud "Bo", a puff of green smoke floated out from the entrance of the cave, like a huge green phoenix, after whistling several times in the air, it flew straight towards Du Nan.

Finally, he plunged into Du Nan's arms!
